register()

Discover the engine through package metadata

from importlib.metadata import entry_points

for entry_point in entry_points(group="tigrbl.engine"):
    if entry_point.module.startswith("tigrbl_engine_memrate"):
        plugin_register = entry_point.load()

How To Choose This Package

Choose tigrbl_engine_memrate when the quick-answer table matches your use case. Choose tigrbl instead when you want the full public facade. Choose a lower-level package such as tigrbl-core, tigrbl-base, or tigrbl-runtime when you are building framework extensions or testing a specific internal boundary.
